LAMP.

Specification of Letters Patent N 0. 28,855, dated June 26, 1860.

To all whom it may concern:

Be it known that I, ELIAS J. HALE, of Foxcroft, in the county of Piscataquis and State of Maine, have invented a new and useful Improvement in Lamps; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which Figure 1, is a side elevation of a lamp cap or burner provided with my invent-ion. Figs. 2, and 3, are transverse sections thereof. Fig. 4, is an underside view of the deflector or cone and the secondary air guard arranged within it.

The nature of my invention consists in so combining or arranging a tubular air guard within and with the cone or deflector and with respect to the wick tube, that air passing up through the cone or deflector, shall be caused to circulate not only against the sides and edges of the flame on the wick (when inflamed) but against the outer surfaces of the sides and ends of the air guard. Also, in so combining an air guard with the cone deflector as to be removable with it with respect to the wick tube as hereinafter specified.

In the drawings, A, denotes the wick tube as applied to the lamp cap, B, whose sides are foraminous or perforated with air inlets as shown at, a, a. This cap B, supports a movable cone or deflector C, arranged with reference to the wick tube and provided with an elongated flame passage or opening I), in its to as shown in the figures. lVithin the sald cone or deflector 0, there is an air guard D, which in horizontal section, is rectangular. The said part D, at its four corners touches and is fastened to the inner surface of the cone, or deflector C, and so as to form within it four segmental air passages, d, e, f, 9, extending about the outer sides and edges of such part, D. The air guard, D, should also have a space between it and the wick and about the same so that air may pass through such guard D, and against both the opposite sides and the ends of the wick. By the above application of the air guard, D, to the cone deflector, the former is removable from the wick tube with and by and at the same time with the latter.

In my improvement, the edges, as well as the sides of the flame on the wick, have currents of air forced in contact with the air 'guard and the cone deflector, and in consequence thereof an improvement in the combustion of the wick takes place and almost all if not all flickering and smoking of the flame is prevented.

I claim 1. So combining or arrangingatubular air guard D, within or with the cone or deflector C, and with respect to the wick tube, that air passing up through the cone or deflector C, shall be caused to freely circulate not only-against the sides and edges of the flame of the wick (when inflamed) but against the outer surfaces of the sides and ends of the air guard.

2. So combining an air guard with the cone or deflector as to be removable with and by it with respect to the wick tube, as set forth.
